Learn How to Spot Mate in 2: Queenside Attack
This puzzle is a classic middlegame mating net: the attacking side uses a forcing check to drag the king into a worse square and then finishes with a second forcing move.

In classical chess, these short tactical finishes often appear after a queenside attack has already loosened the defender’s pieces.
